System for Visualizing Heart Activation

2. The method of claim 1, wherein the measure for heart activation synchronicity is one of standard deviation (std) of the depolarization (dep) times of the heart; range in depolarization times; standard deviation of the Left Ventricle (LV) or Right Ventricle (RV) only; delay between stimulus and Septum activation.

3. The method of claim 1, further including defining a common node, wherein for each node the step b) includes determining for each node of the plurality of nodes a value representative of a time delay of electrical activation relative to the node and the common node.

4. The method of claim 3, wherein the common node corresponds to an intrinsic activation site of the heart of the patient or an artificial stimulation site on the heart of the patient.

5. The method of claim 1, further including defining a plurality of common nodes, wherein for each node the step b) includes determining for each node of the plurality of nodes a value representative of a time delay of electrical activation relative to the node and the plurality of common nodes.

8. The method of claim 7, wherein the three-dimensional geometric models in the database are representative of subjects that differ in at least one of gender, age, weight, body length, chest circumference, frame size, and body-mass-index.

15. The method of claim 1, further including obtaining location information of one or more actual pacemaker electrodes at the patient's heart.

16. The method of claim 15, wherein the location information of one or more actual pacemaker electrodes at the patient's heart is obtained from the patient-specific three-dimensional geometric model.

17. The method of claim 3, further including obtaining location information of one or more actual pacemaker electrodes at the patient's heart, and wherein the one or more actual pacemaker electrode locations form the common node, possibly in combination with an intrinsic activation site of the patient's heart.

18. The method of claim 6, wherein the patient-specific three-dimensional geometric model of the heart, and optionally at least one of the lungs or the thorax, is derived from an MRI or computed tomography (CT) image.

19. The method of claim 1, wherein the candidate node is selected as the node having the highest measure for heart activation synchronicity or the highest measure for heart activation synchronicity within a group of nodes associated with cardiac veins.

20. The method of claim 1, wherein if the candidate node is selected as the node having the highest measure for heart activation synchronicity within a group of nodes associated with cardiac veins, it is determined whether the measure for heart activation synchronicity associated with the candidate node is within a predetermined acceptance interval, and if the measure for heart activation synchronicity associated with the candidate node is outside the predetermined acceptance interval, a candidate node having the highest measure for heart activation synchronicity is selected from nodes not associated with cardiac veins.
